Shortly after the episode aired, Daniel Ingram posted the lyrics on his Facebook wall under the title "A Circle of Friends." There were numerous differences to the song that actually aired, and Ingram posted a second, amended version soon thereafter. The only differences to the version transcribed below are: "Fire of Friendship" is capitalized, and the final line is rendered as "A circle of friends we'll be 'til the very end."

An extended version of the song serves as the tenth track on the holiday album It's a Pony Kind of Christmas, making it the only track from the show to appear on the 2015 edition of the album.

According to a Rolling Stone article, "Ingram considered [The Heart Carol] to be a 'real brony anthem' when he wrote it."[6]
